Well, since you brought up Revengeance, they announced story DLC for that in April where you play as Sam in one, and LQ-84i in the other.
As for DmC, I don't see more story DLC after Vergil's Downfall. Like the above poster said, maybe some more costumes and a Bloody Palace for him but yeah. They should've just gave him the mode too considering he has Angel and Demon attacks.. --- PSN: KazimusPrime // XBL: xKazerux http://card.psnprofiles.com/1/KazimusPrime.png
Vergils bloody palace would be impossible to make, his story is too short, there is only 2 bosses it would end up being like 50 levels long. dantes was only 100 it just would not work with this game. I would love more dlc but i think its done for
